Beschreibung
Zusammenfassung:	A diaphragm for acoustic equipment wherein a surface-hardened layer of SiC film is formed, eg by vapour deposition, on the surface of a diaphragm substrate comprising a full or glassy carbonaceous layer. The diaphragm has superior acoustic characteristics by utilising the superior physical characteristics of carbon and can be used effectively as a diaphragm for digital-audio equipment.
